How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
A JSON response containing a list of stablecoins with their DeFi-relevant properties and metrics such as yield, liquidity, collateral type, and on-chain data, sourced from Sperax's AI-powered intelligence layer.
Example use cases
Yield comparison for DeFi portfolio
“Show me all the stablecoins tracked by SperaxOS with their current yield and liquidity data so I can figure out which one to put my idle USDC into.”
Stablecoin risk profiling for agent
“Fetch the full list of stablecoins from Sperax's DeFi intelligence API including their properties — I need to assess collateralization and risk profile for each one.”
Real-time DeFi dashboard data
“Get me the latest stablecoin metrics from SperaxOS right now — I'm building a live DeFi dashboard and need up-to-date data on all tracked stablecoins without signing up for an API key.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/v1/data/stablecoins?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, AI-curated stablecoin data from the DeFi ecosystem without setting up an API key — ideal for agents that can pay per-request with USDC on Base via x402. Prefer this over generic crypto data APIs when you specifically need stablecoin intelligence with DeFi-native metrics.
Side effects
- 402 Payment Required if x402 USDC payment on Base is not included or insufficient
- Invalid or malformed properties filter returns empty or error response
- Network or RPC issues on Base chain delay response
- Stablecoin data may be temporarily stale if on-chain indexing lags
